Could stainless magnesium replace aluminium in cars and aeroplanes? This calcium–magnesium alloy has implications for carbon emissions
German scientists have created a clever alloy with a very low corrosion rate by alloying pure magnesium with tiny amounts of calcium. Using a lighter metal like stainless magnesium rather than aluminium in cars and aeroplanes could reduce fuel consumption and carbon dioxide emissions.
You can use this article to introduce a lesson on alloys and corrosion with your 14–16 chemistry students. Download the accompanying starter slide for use in your classroom.
